IMPROVEMENT IN COAL-OIL BURNERS.

' Specification forming part of Letters Patent No; 35,533, dated June10, 1862.

To all whom it may concern.-

. Beit known thatI, WILLIAM O. B. MERRILL, of Philadelphia,Pennsylvania, have invented aSmoke-(Jonsumer forCoal-Oil-LampBurners;

and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being-had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists of a metal plate having certain projections andarranged within the perforated easin g of a coal-oil-lamp burner in themanner described hereinafter, so that a plentiful supply of air may bedirected to the sides and baseof the flame, and the smoke therebyeffectually consumed.

In order to enable others to make and use my invention, I will nowproceed to describe its construction and operation. I

On reference to the accompanying drawings,

which form a part of this specification, Figure 1 is a sectional view ofthe burner; Fig. 2, a plan, View of the smokeconsumer detached from theburner; Fig. 3, a View of the plate of which the smoke-consumer iscomposed;

and Fig. 4, a transverse sectional view on the line 1 2, Fig. 1.;

Similar letters refer to similar pa rts throughout the several views.

A'is the outer-perforated casing of an ordinary burner of a coal-oillamp, and is provided with the usual screwed projectioma, for attachmentto the rcservoir,-and with a tube, B, for receiving a tlatwiek whieh canbe raised and lowered by means of the usual cog-wheels, (3.

Within the casing A, and near the upper edge of the same, is a ledge, e,and on this ledge rests the smoke-consumer, the form of and method ofconstructing which will be best understood on reference to Figs. 2 and3. A

flat plate of thin brass or other metal is re duced, by stamping andcutting or otherwise, to the form represented in Fig. 3, an oblong hole,I), for admitting, the wick-tube being formed in themiddle of the plate.

The two projections d and d are turned up so as to assume the form andrelative position illustrated in Fig. 1, the curved projections f fretaining their original form,so as to fit snugly within the casing Aand rest on the ledger). V I.

It will be observed that the air has free access to the top of thewick-tube and base of the flame by passing in the'opposite directionspointed out by the arrows, Fig. 4, between the two turned-up projections01 and d.

In other coal-oil-la1np burners the air directed to the base of theflame (a point where the most plentiful supply is necessary) is limitedby the contracted passages through which it hasto pass. In my improvedburner, however, the base of the flame is so exposed to an unlimitedsupply of air that the greater portion of the carbonaceous products ofcombustion is consumed. The air which finds its way through theperforations to the interior of the casing A becomes partially heatedtherein,and,passingupward through the openings w a: formed in the plateby the turning up of the projections d and d, is directed to theopposite side of the flame, causing the latter to burn with brilliancyand to consume whatever carbon may escape the effect of the plentifulsupply of air admitted to the base of the It will be seen that myimprovement, cheap and simple asit is, effectually accomplishes the samepurpose as the many complex devices heretofore used in connection withcoaloil lamps for attaining the same results, and that the improvementmay be applied to any of the' ordinary burners and used either with orwithout a chimney, the consumption of smoke being so effectuallyaccomplished that a chimney may, is desired, be dispensed with.

In applying my improvement to the burner care should, be taken toproperly adjust the projections d and d in respect to each other; Thismay be easily'done by bending the projections and altering theirrelative positions until the'flame burns with brilliancy and freedomfrom smoke.

I claim as my invention, and desire to secure by Letters Patent-' Thesmoke-consumer composed of a metal plate with the flat projectionsff andturnedup projections d and (1, when arranged within the perforatedcasing A of a coal-oil-lamp burner, as and for the purpose herein setforth.

In testimony whereof I havesigned my name to this specification in thepresence of two subscribing witnesses. i
